When this creature enters, exile target creature card with mana value 3 or less from your graveyard. Create a token that's a copy of it. That token gains haste. Sacrifice it at the beginning of the next end step.
Whenever one or more cards leave your graveyard, each opponent loses 1 life and you gain 1 life.
